Two legends in "Survivor" history set their sights on one another in an epic showdown; a castaway introduces the spy shack 2.0.

The castaways must figure out which attribute -- brains, brawn or beauty -- will be the thing that helps them win the most grueling competition yet.

Survivors have a tribe swap; the game starts from scratch for one set of castaways; one castaway leaves his tribemates stranded in the ocean so he can search their camp for the immunity idol.

A castaway retrieves an idol from great heights; two castaways in the beauty tribe become friends; a taxing physical challenge could lead to immunity and rewards.

A dramatic twist in the game sends shock waves through the tribes; the castaways face a classic immunity challenge.

Friends become enemies when one castaway is caught trying to sabotage another's game.
